Abstract: A transportation system including a guide way defining multiple surfaces, each extending at an angle to the ground and at least one track mounted on one of the surfaces. A vehicle is adapted for movement along the guide way and is adapted to engage a corresponding track on the one surface when the vehicle is moving along the guide way in one direction and is adapted to engage a corresponding track on another surface when the vehicle is moving along the guide way in another direction.

Abstract: This invention relates to a process for fabricating a metal-oxide-semiconductor device and to the semiconductor device which has enhanced charge mobility due to the inclusion of a thin layer of intrinsic semiconductor which provides a "fast track" charge channel directly at the accumulated inversion layer. The particular semiconductor device described is the enhanced mobility metal-oxide-semiconductor field effect transistor EMMOSFET having the intrinsic layer from about 100 .ANG. to about 1000 .ANG. thick. The intrinsic layer provides a low resistivity channel between the source and drain of the EMMOSFET resulting in an increase in device speed and a decrease in device heat generation.
